“…[4] Similarly, an abstract describing 94 patients with post-thrombotic venous occlusion found that stents placed across the inguinal ligament had significantly worse secondary patency rates after 1 year than those placed supra-inguinal ligament (82% vs 100%; p < 0.05). [5] Despite these findings, the authors of both studies contend that stenting across the inguinal ligament is safe and effective, given the relatively high, albeit significantly lower, patency associated with stents that cross the inguinal ligament. However, neither of these studies considered a comprehensive set of important covariates and potential confounders in their analyses of longitudinal patency rates.…”

Toward Data-Driven Learning Healthcare Systems in Interventional Radiology: Implementation to Evaluate Venous Stent Patency

We developed a code and data-driven system (learning healthcare system) for gleaning actionable clinical insight from interventional radiology (IR) data. To this end, we constructed a workflow for the collection, processing and analysis of electronic health record (EHR), imaging, and cancer registry data for a cohort of interventional radiology patients seen in the IR Clinic at our institution over a more than 20-year period. As part of this pipeline, we created a database in REDCap (VITAL) to store raw data, as collected by a team of clinical investigators and the Data Coordinating Center at our university. We developed a single, universal pre-processing codebank for our VITAL data in R; in addition, we also wrote widely extendable and easily modifiable analysis code in R that presents results from summary statistics, statistical tests, visualizations, Kaplan-Meier analyses, and Cox proportional hazard modeling, among other analysis techniques. We present our findings for a test case of supra versus infrainguinal ligament stenting. The developed pre-processing and analysis pipelines were memory and speed-efficient, with both pipelines running in less than 2 min. Three different supra-inguinal ligament veins had a statistically significant improvement in vein diameters post-stenting versus pre-stenting, while no infra-inguinal ligament veins had a statistically significant improvement (due either to an insufficient sample size or a non-significant p value). However, infra-inguinal ligament stenting was not associated with worse restenosis or patency outcomes in either a univariate (summary-statistics and Kaplan-Meier based) or multivariate (Cox proportional hazard model based) analysis.

This consensus statement of Russian experts is based on a review of the relevant literature on the prevalence, diagnosis, and treatment of non-thrombotic and post-thrombotic venous obstruction, as well as management of patients after venous stenting. In the Part 1 we discussed the clinical manifestations of venous obstruction, the role of duplex ultrasound scan, CT venography, MR venography, direct venography, and intravascular ultrasound scan, as well as typical findings obtained by using these methods. The authors mentioned the functional assessment of venous outflow in healthy subjects and in those with obstruction and changes in them after the intervention. In conclusion, the authors formulated the suggestions for clinical recommendations on the diagnosis of chronic venous obstruction.
